     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a support device for a skater. More particularly, the present invention relates to a device which permits a skater to develop balance and to practice skating techniques while supported by the device. 
     2. Information Disclosure Statement 
     When amateur skaters contemplate the grace and skill of professional skaters such as John Cousins performing in international competitions, such skaters are enthused to attempt to imitate some of such performers skating techniques. 
     Unfortunately, even the most simple techniques such as skating in reverse or turning from forward to reverse skating often result in several falls which may unnerve all but the most determined skaters. 
     The present invention seeks to overcome the fears and dangers associated with learning the aforementioned skating skills. The device according to the present invention also enables the user to rapidly develop balance and confidence such that the beginner skater can quickly master the art of figure skating and the like. 
     Basically, the present invention provides an adjustable frame with casters thereon for supporting the skater thereby allowing the user to maintain balance while skating either on ice or while roller skating on a roller skating rink. 
     Therefor, it is a primary objective of the present invention to provide a support device which overcomes the aforementioned fears and dangers associated with learning to skate. 
     Another object of the present invention is the provision of a support device which enables a more advanced skater to develop sophisticated skating techniques without any fear of losing balance. 
     Another object of the present invention is the provision of a support device which enables a skater to practice in a very small area for example in the users garage or recreation room. 
     Other objects and advantages of the present invention will become evident to those skilled in the art by a consideration of the detailed description contained hereinafter taken in conjunction with the annexed drawings. 
     SUMMARY OF THE INVENTION 
     The present invention relates to a support device for supporting a skater. The device comprises a first extensible frame of inverted U-shaped configuration, the first frame having a first and a second end. A first handle is rigidly secured to the first frame between the first and second end for supporting the skater. The device also includes a second extensible frame of inverted U-shaped configuration, the second frame being spaced and parallel relative to the first frame. The second frame having a first and a second extremity. 
     A second handle is rigidly secured to the second frame between the first and second extremities for supporting the skater such that in use of the device, the skater is disposed between the handles. First and second laterally extensible supports extend between the first and second frames such that, in use of the device, the skater is disposed between the supports. The arrangement is such that adjustment of a first distance between the supports and a second distance between the frames is permitted so that the device provides adjustable support according to the size and skating ability of the skater. Casters are secured to the ends and the extremities for permitting the skater to develop balance and to practice skating techniques while the skater is supported by the handles. 
     In a more specific embodiment of the present invention, the first frame includes a first and a second downwardly extending limb, the first and second limbs including respectively, a first and second selectively lockable extension means for permitting selective adjustment of the height of the first handle relative to the caster means. Additionally, the second frame includes a third and fourth downwardly extending limb, the third and fourth limbs including respectively a third and fourth selectively lockable extension means for permitting selective adjustment of the height of the second handle relative to the caster means. The first and second frame further include first means disposed between the first and second limbs for selectively locking the first distance between the supports and second means disposed between the third and fourth limbs for selectively locking the first distance between the supports. 
     The first means includes a substantially horizontally disposed member, and an arm slidably cooperating with the member such that adjustment of the first distance is permitted. The second means also includes a substantially horizontally disposed further member and a further arm slidably cooperating with the further member such that adjustment of the first distance is permitted. 
     The member and the arm define a plurality of axially spaced aligned holes. Additionally, the first means further includes a locking pin removably extending through a pair of the aligned holes for locking the member and the arm relative to each other. The further member and the further arm define a further plurality of axially spaced aligned holes. The second means includes a further locking pin removably extending through a further pair of aligned holes of the further plurality of holes for locking the further member and the further arm relative to each other. 
     The first handle includes a hand grip disposed substantially horizontally. A portion is rigidly secured to the first frame and extends generally outwards and then downwards relative to the skater such that the portion is disposed between the first frame and the hand grip. The second handle includes a further hand grip disposed substantially horizontally and a further portion is rigidly secured to the second frame and extends generally outwards and then downwardly relative to the skater such that the further portion is disposed between the second frame and the further hand grip. The arrangement is such that in use of the device, when the skater grips the respective handles, the wrists of the skater are braced and supported by the portion and further portion respectively so that the control and balance of the skater is enhanced. 
     The device also includes an auxiliary handle secured to the first frame and axially spaced relative to the first handle. A further auxiliary handle is secured to the second frame and is axially spaced relative to the second handle. The arrangement is such that in use of the device by a more experienced skater, the skater grips the respective auxiliary handles while the first and second handles support the upper arms of the skater. 
     The first support includes a horizontally disposed first section rigidly secured to the first frame between the first handle and the first end of the frame. A first further section telescopically cooperates with the first section. A fastening means is included for adjustably fastening the first section and a first further section together such that in use of the device, the second distance between the frames is established. The second support includes a horizontally disposed second section rigidly secured to the first frame and a second further section telescopically cooperating with the second section. A further fastening means is included for fastening the second section and the second further section together for establishing the second distance between the frames. 
     Many modifications and variations of the present invention will be apparent to those skilled in the art on consideration of the detailed description contained hereinafter taken in conjunction with the annexed drawings. However, such modifications fall within the spirit and scope of the present invention as defined by the appended claims. 
     Included in such modifications would be securing means for removably securing the auxiliary handles to the respective frames in order to assist in packaging and transportation of the device.
